Question 3

Show transcribed image textA pn junction has NA = 5 times 1018cm-3 and ND = 5 times 1016cm-3. At equilibrium, determine the minority carrier densities at the edges of the depletion layer; If a forward biasing voltage of 0.65 V is applied to the junction, Recalculate the minority carrier densities at the edges of the depletion layer. What are the excess minority ( delta n, delta p) carrier concentrations at the edges? Estimate the majority concentration changes. Under a reverse bias of 2.0V, calculate the minority concentrations at the depletion edges.
